Make a sleep schedule and stick to it.

Try to go to bed and get up at the same time every day – even on weekends. Although you may feel like you're catching up on sleep by sleeping in at the weekend, it doesn't fully compensate for sleep deprivation during the week. Over time, irregular sleep can also lead to health problems, including increased risk of obesity, diabetes and cardiovascular disease. 

WHY IT HELPS:
When you get your body used to falling asleep and waking up at the same time, you improve your circadian rhythm. This makes it easier to fall asleep in the evening and wake up in the morning. Regular sleep leads to better concentration, memory and mood.
